Perhaps this is a better comparison. Look where the flow is going on the RB....






if we compare to the other day where the bargeboard flow conditioner is isolated, you can see exactly where the flow pass the sidepods, which looks pretty good i think

Let us rephrase that. Why do you think air is coming from up that high? The way I was expecting it is that air was hitting the input more straight (parallel to ground), the way you draw it air is already coming downwards. I think you are correct there and that is the part that amazes me. I didn't expect air to be going down that early.

Like I said - borderline story telling... Jokes aside, I have some Formula Student CFD experience and intuition and those streamlines look decently uniform suggesting that this is how the airflow goes in this zone. Flap connecting barge board and tub is very aggressive, front wishbones are at an angle so that's one part of why it bends that way. The other - leading edge on the floor is bigger and has a bigger radius allowing more air to come under to this very low pressure zone, thus creating stronger suction zone. Diffuser being bigger and stronger probably helps also, as downstream flow is also influencing upstream flow (all things being equal, diffuser creating stronger suction will create stronger suction around floor leading edge etc)...

BTW: doesn't matter if we are right/wrong, as long as we feel good about our theories

Just from thumb sucking I'd say the pressure drag looks a little high on the macca just in front of the lower edge of the intake. I did speculate they might add a mp4-23??? style vane there a few pages back.... Or they could do an STR and extend the lower part of the pod forward. Of course we also don't know what they are doing around the floor that might help 'pull down' the air in this manner in addition to the bargeboard turning vane and suspension.

What is that "bulge" underneath the sidepod inlet behind the bargeboard on the floor ??

That's a lot of different Mesuring devices at once.

thats the raised front floor, new rules this year allow them to raise it x2 compared to last year and everybody does to allow more flow under

It's the front of the floor shaped around the impact structure.

Rigidity is everything, another mount point?

Visflow from the McLaren actually looks pretty good. I think the overal aero/suspension package on the McLaren is on top of its game, better than Red Bull, its only lacking the most important thing... Horses. And. Power.

Faithful following of the rules today, guys! Keep it up. I know the constant breaking down of the car is frustrating. Keep ventilating that in the team thread and testing thread (not in the PU thread and here).

Dual air inlets under the nose.
